In the steel cord production and processing workshop, I-shaped wheels often need to be circulated in different steel cord processing procedures. In traditional processing workshops, operators generally circulate I-shaped wheels in the workshop by manual handling combined with trolley transportation. This transportation mode of I-shaped wheels greatly increases the workload of operators. Whether it is an I-shaped wheel full of steel cord or an empty I-shaped wheel, it is difficult for manpower to repeatedly bear its weight for a long time.

Operators can use the crane to transfer the I-shaped wheels. In this process, the problem of how to clamp the I-shaped wheels on the crane is involved. In the prior art, the I-shaped wheels are hoisted by tying them with steel wire ropes, or by using U-shaped hoists inserted into the mandrel of the I-shaped wheels. However, in actual use, the above hoisting structure is complicated to install and disassemble, and the I-shaped wheels lack stability during transfer, which easily brings hidden dangers to production safety.

[0039] In order to better understand the technical content of the present invention, specific embodiments are given and described as follows in conjunction with the accompanying drawings.

[0040] [Vertical handling tool for I-shaped wheels]

[0041] The first aspect of the present invention provides a vertical transport tool for an I-shaped wheel. The transport tool is intended to be used in conjunction with a crane system and is mainly used to transport an I-shaped wheel in a vertical state. The I-shaped wheel in a vertical state refers to an I-shaped wheel whose axis is in a vertical direction. The characteristic of this I-shaped wheel is that the edge of the wheel disc of the I-shaped wheel can be used as a gripping point. The I-shaped wheel can be clamped by gripping the edge of the wheel rim with the transport tool, and moved to a suitable position using the crane system, for example, from a full-reel area for taking up the line to a trolley.

[0042] Combination Figure 1 As shown, the transport tool mainly includes a lifting plate 10, a sleeve 20, a pull rod 30, a positioning ring 40, and a plurality of lifting claws 50. The lifting plate 10 is provided with at least three lifting claw grooves 11. The sleeve 20 is connected to the top of the lifting plate 10. The pull rod 30 is arranged on the inner side of the sleeve 20 and is slidably connected to the sleeve 20. A lifting ring 31 is provided on the top of the pull rod 30, and the lifting ring 31 is connected to the overhead lifting system. The positioning ring 40 is connected to the top of the sleeve 20 and is sleeved on the outer wall of the pull rod 30. Each lifting claw 50 is connected to a lifting claw groove 11.

[0043] In this way, the lifting platform 10 constitutes the supporting structure of the lifting claw 50, and the cooperation of the sleeve 20 and the pull rod 30 can drive the lifting claw 50 to complete the switching of the grasping and releasing positions. Since the sleeve 20 and the lifting platform 10 are relatively fixed, during operation, it is only necessary to control the position of the lifting platform 10 through the overhead crane, and then control the position state of the pull rod 30 to realize the grasping and releasing of the I-shaped wheel by the lifting claw 50.

[0044] Further, combined with Figure 2 As shown, the upper end of each lifting claw 50 is connected to the bottom of the pull rod 30. When the pull rod 30 slides upward relative to the sleeve 20, the lower ends of the multiple lifting claws 50 move inward synchronously until they reach a clamping position. In the clamping position, the lifting claws 50 can clamp the rim of the I-shaped wheel. When the pull rod 30 slides downward relative to the sleeve 20, the lower ends of the multiple lifting claws 50 move outward synchronously until they reach a release position. In the release position, the lifting claws 50 are separated from the rim of the I-shaped wheel.

[0045] It can be seen that when the pull rod 30 moves downward relative to the sleeve 20, the lifting claw 50 opens and is in a released position, and when the pull rod 30 moves upward relative to the sleeve 20, the lifting claw 50 retracts and is in a clamping position. Since the pull rod 30 is always in a state of being pulled upward when the overhead crane system is lifting and transporting tools, it is beneficial to keep the lifting claw in a clamped state. Only when the user manually presses the pull rod 30 downward, the lifting claw 50 opens to clamp the edge of the I-shaped wheel 100.

[0046] Furthermore, a limit groove 33 is provided on the outer wall of the pull rod 30, and a positioning pin 42 which can be inserted into the limit groove 33 is provided on the positioning ring 40. The positioning pin 42 slides in the limit groove 33 to limit the extreme position of the pull rod 30 relative to the sleeve 20, so that the lifting claw 50 can switch between the clamping position and the release position and remain in the clamping position or the release position.

[0047] Thus, in order to keep the lifting claws 50 in a relatively stable position when clamping and releasing the spool 100, the provided limiting groove 33 can control the position state of the pull rod 30. That is, before clamping the spool, the user holds the pull rod 30 in the depressed position, so that there is no need to continuously press the pull rod 30. After the tool reaches above the spool 100, the holding state of the lifting claws 50 is released, so that the lifting claws 50 can move from the release position to the clamping position, and then the pull rod 30 is controlled to be held in the clamping position. In this way, the spool will not fall off during the hoisting process.

[0048] Combined with Figure 3 and Figure 4 As shown, the positioning ring 40 can rotate relative to the sleeve 20. Among them, a circular groove 43 is provided on the part of the positioning ring 40 extending into the sleeve 20, and a positioning screw 22 is provided on the outer wall of the sleeve 20. The positioning screw 22 extends into the circular groove 43, so that the positioning ring 40 and the sleeve 20 are axially fixed relative to each other along the axis of the sleeve 20.

[0049] When assembling the positioning ring 40, before the positioning screw 22 is installed, the positioning ring 40 is inserted into the upper end of the sleeve 20 to make the positions of the circular groove 43 and the hole of the positioning screw 22 correspond, and then the positioning screw 22 is inserted into the sleeve 20 so that the positioning screw extends into the circular groove 43. In this way, the positioning ring 40 can only rotate relative to the sleeve 20 and is fixed in the axial direction.

[0050] Combined with Figure 4 As shown, the limiting groove 33 includes a first strip-shaped groove 331, a second strip-shaped groove 332 and a third strip-shaped groove 333. The second strip-shaped groove 332 is arranged along the axis direction of the pull rod 30. The first strip-shaped groove 331 is connected to the top end of the second strip-shaped groove 332, and the third strip-shaped groove 333 is connected to the bottom end of the second strip-shaped groove 332. The first strip-shaped groove 331 and the third strip-shaped groove 333 are arranged along the circumferential direction of the pull rod 30.

[0051] Among them, the first strip-shaped groove 331, the second strip-shaped groove 332 and the third strip-shaped groove 333 are in a "C" shape. The two horizontal grooves are the first strip-shaped groove 331 and the third strip-shaped groove 333, and the one vertical groove is the second strip-shaped groove 332.

[0052] In this way, when the positioning pin 42 slides in the second strip-shaped groove 332, the lifting claws 50 move between the clamping position and the release position. Especially when the positioning pin 42 is at the top of the second strip-shaped groove 332, the pull rod 30 is located at the lower limit position relative to the sleeve 20, and at this time the lifting claws 50 are in the release position. When the positioning pin 42 slides in the first strip-shaped groove 331, the lifting claws 50 are held in the release position. When the positioning pin 42 is at the bottom of the second strip-shaped groove 332, the pull rod 30 is located at the upper limit position relative to the sleeve 20, and at this time the lifting claws 50 are in the clamping position. When the positioning pin 42 slides in the third strip-shaped groove 331, the lifting claws 50 are held in the clamping position.

[0053] Furthermore, the widths of the first strip groove 331 and the third strip groove 333 match the outer diameter of the positioning pin 42. In this way, when the pull rod 30 is at the upper limit position and the lower limit position, no shaking occurs.

[0054] Furthermore, the outer wall of the positioning ring 40 is also connected with a handle 41. In this way, the rotation angle of the positioning ring 40 can be controlled by the handle 41, and the relative positions of the sleeve 20 and the pull rod 30 in the axial direction can also be controlled by the handle 41.

[0055] Combination Figure 1 and Figure 2 As shown, a cavity is provided inside the sleeve 20, and a connecting structure 32 extending into the cavity is provided at the bottom of the pull rod 30. The connecting structure 32 is connected to the hanging claw 50 through a connecting rod 321 extending out of the cavity. When the pull rod 30 slides along its axial direction relative to the sleeve 20, the angle of the connecting rod 321 relative to the pull rod 30 changes.

[0056] In this way, the bottom of the pull rod 30 is connected to the hanging claw 50 through the connecting rod 321, and the displacement of the bottom of the pull rod 30 can be transmitted to the hanging claw 50 through the connecting rod 321, thereby controlling the hanging claw 50 to complete the position switching.

[0057] Furthermore, the outer wall of the sleeve 20 is provided with a slot 201 connected to the cavity, and the connecting rod 321 passes through the slot 201 . The first end of the connecting rod 321 is hinged to the connecting structure 32 , and the second end is hinged to the hanging claw 50 .

[0058] In this way, the displacement of the pull rod 30 inside the sleeve 20 can be transmitted to the outside of the sleeve 20 , and the pull rod 30 is arranged inside the sleeve 20 , which is conducive to controlling the position state of the pull rod 30 through the positioning ring 40 .

[0059] Combination Figure 3 As shown, the lifting claw 50 is constructed as a Z-shaped structure, including a first connecting structure 51 in the middle area, a second connecting structure 52 in the upper area and a clamping portion 53 in the lower area, the first connecting structure 51 is hingedly connected to the connecting structure 32, the second connecting structure 52 is hingedly connected to the lifting claw groove 11, and the clamping portion 53 is configured to have a hook-shaped structure extending toward the inner side of the hanging plate 10.

[0060] Specifically, the clamping portion 53 is closer to the first connecting structure 51 than the second connecting structure 52 is to the first connecting structure 51. Therefore, the lifting claw 50 acts as a lever structure. When a smaller force is applied to the second connecting structure 52, a larger force can be generated at the clamping portion 53. Moreover, when the pull rod 30 is in the upper limit position, the connecting rod 321 is perpendicular to the pull rod 30, and the second connecting structure 52 is perpendicular to the connecting rod 321. Therefore, if the clamping portion 53 moves outward, it can only compress the connecting rod 321, or the angle of the connecting rod 321 changes. It can be seen that the lifting claw 50 has a strong self-locking ability when it is in the clamping position, and can maintain a stable state of clamping the I-shaped wheel 100.

[0061] Furthermore, when the pull rod 30 moves downward, the clamping portion 53 rotates around the first connection structure 51 toward the outside of the hanging plate 10 , and when the pull rod 30 moves upward, the clamping portion 53 rotates around the first connection structure 51 toward the inside of the hanging plate 10 .

[0062] During the lifting process, the pull rod 30 always tends to move upward, so the clamping portion 53 will keep clamping the I-shaped wheel.

[0063] In an optional embodiment, a slot is provided in the center of the hanging plate 10, and the positioning plate 21 at the bottom of the sleeve 20 is inserted into the slot, and the positioning plate 21 is fixed to the hanging plate 10 by screws. In this way, the sleeve 20 and the hanging plate 10 are convenient to assemble.

[0064] Preferably, the positioning plate 21 at the bottom of the sleeve 20 can extend to the bottom of the hanging plate 10, and in particular can be inserted into the shaft hole of the I-shaped wheel, so that it is helpful to position the hanging plate 10 at the center of the I-shaped wheel.

[0065] [How to transport the I-shaped wheel]

[0066] The second aspect of the present invention provides a technical solution, a method for transporting an I-shaped wheel, using the above-mentioned vertical transport tool for the I-shaped wheel, comprising the following steps:

[0067] Step 1: Use the overhead crane system to move the handling tool to the top of the I-shaped wheel to be handled;

[0068] Step 2, rotate the positioning ring 40 and adjust the position of the positioning pin 42 so that the positioning pin 42 is in the first strip groove 331, and the hanging claw 50 is kept in the release position;

[0069] Step 3, the hanging plate 10 is closely attached to the wheel surface of the I-shaped wheel and is approximately in the center, and the hanging claw 50 is located on the outer side of the wheel surface of the I-shaped wheel;

[0070] Step 4, rotate the positioning ring 40 to make the positioning pin 42 enter the second strip groove 332, and at the same time pull the pull rod 30 upward to make the lifting claw 50 in the clamping position. At this time, the lifting claw 50 clamps the wheel surface of the I-shaped wheel;

[0071] Step 5, rotate the positioning ring 40 so that the positioning pin 42 is in the third strip groove 333, and the hanging claw 50 is kept in the clamping position;

[0072] Step 6: Use the overhead crane system to transfer the clamped spool to the target position until the bottom of the spool is supported by the target area;

[0073] Step 7, rotate the positioning ring 40 and adjust the position of the positioning pin 42 to disengage the positioning pin 42 from the third strip groove 333, press the pull rod 30 downward, move the hanging claw 50 from the clamping position to the release position, and release the I-shaped wheel;

[0074] Repeat steps 1 to 7 until the spool is moved.

[0075] Combination Figures 5 and 6 As shown, in a specific process of clamping the I-shaped wheel, the user holds the handle 41 with one hand, grabs the pull rod 30 with one hand, holds the handle 41 with one hand, and presses the pull rod 30 downward with the other hand to put the lifting claw 50 in the release position, as shown in FIG. Figure 5 As shown, the position of the tool is controlled to make the upper end surface of the hanging plate 10 and the I-shaped wheel 100 fit together, and then the pull rod 30 is pulled upward to combine Figure 6 As shown, the claw 50 changes from the release position to the clamping position, and then the handle 41 is rotated to move the positioning pin 42 to the third strip groove 333, as shown in FIG. Figure 6 As shown, at this time, the lifting claw 50 remains in the clamping position, and the I-shaped wheel can be transferred to the target by using the overhead crane system.

[0076] In combination with the above embodiments, the handling tool proposed in the present application is used in conjunction with the overhead crane system in the workshop. Specifically, the pull rod arranged in the sleeve is moved up and down to control the lifting claws on the periphery of the lifting plate to complete the clamping and releasing actions. During operation, the user can control the handle with one hand to adjust the position of the tool and the state of the positioning ring, and control the pull rod with the other hand to adjust the clamping and release states of the lifting claws. The clamping and releasing actions of the opposing I-shaped wheels can be achieved through the coordination of both hands, thereby improving the efficiency of I-shaped wheel handling and transfer in the workshop. The tool is simple and quick to operate, with high clamping reliability. There is no risk of falling off during overhead crane transportation, and the safety factor is high.
